POWER PLANT.

Specification of Letters Patent.

Patented Jan. 29, 1907.

Application filed October 16,1906. Serial No. 283059.

To a, whom it may concern:

Be it known that I, FRANK YEoMAN, a citizen ofthe United States, residing at Oroville in the county of Butte and State of Cal' ornia, have invented certain new and useful Improvements in Power Plants; and I o be a full, clear, and exact description 0 he invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in power plants of the hydro-electric type.

The object of the invention is to provide a giver plant of this character-which willbe so posed in the wall of a dam, canyon, or any other similar place in which a body of water is' confined so that it cannot be injured or in any Way affected by the undue rise of the river, stream, pond, ake or other body of With the above and other objects in view the invention consists of certain novel features of construction, combination, and arran ement of parts, as will be hereinafter desc'ri ed and claimed.

In the 'accompanying drawings, Figure 1 is avertical longitudinal sectional view through embodiment of my invention; and Fig. 2 is a vertical transverse sectional view through the same.

In the practice of my invention I mount in which confines a body of water, one or more water wheels or turbines 2, which I connect to electric generators 3. The water-turbines form and construction and may be connected direct, as shown in Fig. 1 of the drawings, or in any'other suitable manner. As shown, the turbine 2 is mounted adjacent to the lower end of a well 4, which is formed in the wall 1 and has adjacent to its upper end an intake-opening 5. The amount of water assing through said intake may be controlled in any suitable manner. As shown, a sliding gate 6 is provided and operated by mechanism 7 mounted upon the top of the wall. This mechanism 7 comprises two rack-bars 8, which are secured to the to of. the gate 6 and engage inions 9 upon a s aft 10, mounted in suita le bearings 11. In said bearin' is also mounted a arallel'shaft 12, which is connected to the s aft 10 by a pair of meshin ears 13 and which has upon its ends cran handles 14 and pawl-andratchet locking devices 15. It will be seen that when the crank-handles 14 are rotated the gate 6 may be raised and lowered to open and close the intake 5.

The .water passing through the well 4 enters the turbine-casing and is discharged from each end of the latter through dischar epassages 16, which open into horizontal ydisposed outlet-passages 17, which extend transversely of the wall 1.

The electric generator 3, as clearly shown in Fi 2 of the drawings, is mounted in a chain er 18', formed in the wall 1, adjacent to the lower end of the well. Access is had to said chamber through a manway or passa e 19, which leads from the u per ortion 0 said chamber to the top of t 1e wa l. The top of the well 4 and the top of the passage 19 ma be closed by ca s or covers 21 22. The wal s of the well, 0 amber, and other passageways may be constructed of metal, masonry, or any suitable material.

The manner of practicing m invention and the advantages thereof wil be readily understood from the foregoing description, taken in connection with the accompanying drawings. It will be seen that by mounting the direct connected power units in the water-tight compartments in the wall of a dam, canyon, or the like said parts will be protected, so that they cannot be injured by any undue rise of the water confined by such dam or wall.

Vihilc l. have shown and described the preferred embodiment of my invention, it will be understood that I do not wish to be limited to the precise construction herein set forth, since various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

- Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

A power plant comprising a wall having a well open at its up or end at the top of the wall, provided wit 1 a water-inlet opening near its u per end, a chamber at the bottom of the well a passage leading from said chamber to the top of the wall, water-dischar e igassages leadm downwardly and outward y om said cham er, a turbine having its casing in said chamber at the lower end of and c'ommunicatin with the well, dischargepipes leading cm the turbine-casing to the discharge-passages, an electric generator in the chamber connected to and driven by the turbine, closures for the u per ends of the Well and of the V assage wh c lleads upwardly from the charm er and a gate to open and close the water-inlet opening, substantially as described.

[11 testimony whereof I have hereunto Set my hand. in presence of two subscribing wit messes.
